He is the charming young man Chiharu Nitta met during summer training camp. A city slicker with a beat for nature and lots of hobbies, at first Chiharu shrugged him off, but because she was lonely, and she's in a fight with Kyoichi, she nearly gave in. Though he already had girlfriend waiting in the city, he continued his advances and managed to make Chiharu fall for him. They spent a night together at a lookout point (it is unknown if they actually had sex but it is very much presumed). She gave him a goodbye kiss which was witnessed by Kyoichi. (Source: Wikipedia)
